Title: Health Information Technology Basics

Health Information Technology Basics
  • January 8, 2011
  • by Leola McNeill
  • adapted from
  • Information Technology Basics by
  • June 2009, Kayla Calhoun Dr. Frank Flanders

  • Define information technology.
  • Describe how technology impacts the healthcare
  • Describe Concept of Health Informatics technology
  • Compare and contrast current types of healthcare
    networks information technology (IT)
  • What are long range plans for information
    technology and careers.

Information Technology
  • Method used to
  • Process
  • Protect
  • Store
  • Transmit
  • Retrieve
  • DATA

Health Information Technology (HIT)
  • Information Technology is the wave of the future
    for healthcare management
  • HIT- refers to the technology used to create,
    transmit, store, secure and manage an
    individuals health data.
  • Currently electronic health data is limited to a
    single healthcare system, facility or office.

Concept of using IT in healthcare
  • The concept of interoperable sharing of health
    information will authorized entities access (i.e.
    physician's, billing)
  • IT use in healthcare is a expanding concept to
    have an impact on
  • Enhancing healthcare safety
  • Decrease healthcare cost, and
  • Enhance healthcare quality
  • The need has been recognized by the private
    sectors and at the highest levels of government

Define modern health information technology.
  • Use of computer hardware and software to manage
    health care information
  • Increases legibility

  • The vision is that reliable health-related
    information will exist electronically in a format
    that can be securely and easily accessed by
    authorized agencies to
  • Improve the health of the individual
  • Improve health a community
  • And ultimately of the U.S. population as a whole

Data continued.
  • Health information is obtained, entered
    electronically, stored and retrievable to promote
    continuity among providers
  • Data entered electronically promotes adherence to
    the National Patient Safety Goals (NPSG)
  • The Joint Commission lists the current standards
    and goals on its website
  • http//

Data Storage
  • After data is converted into bits, it can be
    stored in bytes (a string of 8 bits)
  • Primary storage, or memory, is located in the
    hard drive and can be directly accessed by the
    central processing unit (CPU)
  • Secondary storage located outside the computer
    ex disks, CDs, USB sticks, external hard drives
  • Good for security purposes

Challenges of Healthcare Data Protection
  • Prevention of data corruption
  • Limits access to data
  • Disk encryption
  • Backup internal or external copies of data
    files in case of accidental data loss
  • Data masking hiding specific private data
    within a database
  • Data erasure destroys all electronic data on a
    hard drive to maintain privacy if it is discarded
    or reused

Data Processing
  • Conversion of data into usable information
  • Fetches instructions for a program from memory
  • Decodes and reads instructions
  • Portions of the CPU connect and execute
  • Writes back the results to memory

Data Transmission
  • Physical transfer of data over a medium, such as
    copper wire, optical fiber, or wireless
  • Networks enable two or more computers to share
    files, printers, and communicate with each other

Health Information Networks
  • Local Area Network (LAN) contained within one
    healthcare practice or hospital commonly referred
    to as an intranet
  • Wide Area Network (WAN) connects several
    healthcare practices or hospitals
  • Ex Internet

Health Information Networks, continued.
  • Client-server Healthcare organization computers
    are all connected by a central server can be LAN
    or WAN
  • Peer-to-Peer Healthcare facility or office
    practice computers are connected to each other,
    but files are not stored in a central location
    can only be LAN

Health Information Networks, continued.
  • Server large powerful digital storage point
    that performs a service for other computers in a
    network file, print, web, mail is used to
    maintain patient information
  • Use of a server makes it easier to maintain
    security and perform backups when health
    information files are centrally stored
  • Health Information is protected by HIPAA (Health
    Information Privacy and Accountability Act)

  • With the advances in technology, the internet is
    used for obtaining and providing health
  • IP Address each computer has one enables data
    to be sent to and received from a specific
    computer and creates an electronic fingerprint
    for legal purposes
  • E-mail

Data Retrieval
  • Science of searching
  • User enters a query (ex search string on web
    search engine or computer hard drive)
  • Computer information retrieval system scores
    objects in database by relevancy and displays
    those most relevant to the query

Common IT Applications
  • Word processors used to create and edit
  • Spreadsheets used to analyze figures and present
    information with graphs/charts
  • Databases stores information about a set of
    similar items

Common IT Applications
  • Publishing more control over formatting and
    arranging than word processing
  • PowerPoint used in business presentations and
    the classroom to present factual information or
    for persuasive purposes

Careers in Health Informatics
  • Health Professionals use computers and store
    information electronically daily
  • Health Informatics specialists are needed to
    manage those health information systems and
    protect client information.
  • Some jobs in Health Informatics
  • Health Information Management Director
  • Nurse Informatics Specialist
  • Health Information Project Manager
  • Chief Information Officer (CIO)

Top Skills of HIT Professionals are
  • Computer Networking
  • Information Security
  • Database Management
  • Information Storage and Retrieval
  • Risk Management

How fast things change!!!
Mass Data Storage and Retrieval
  • Challenge how to maintain security of
    information on server

Connect the Pieces of the Patient puzzle
  • The information age has created the new career
    field of health information technology.
  • The goal of Health Information technology is to
    use computer hardware and software to manage
    healthcare and patient information.
  • Healthcare professionals use computer systems to
    gather, process, store, protect, transmit, and
    retrieve data.
  • Computers are used in healthcare setting and
    connected to each other by networks, limited.
  • Due to the complexity and extent of healthcare
    network, facilities may have one or more servers,
    which store patient files in a central location.

Summary, continued
  • Health information is being transmitted across
    networks to promote continuity of care for
    patients among providers
  • Common healthcare software applications are word
    processors, spreadsheets, databases, publishing,
    and PowerPoint
  • Electronic Health Information companies exist to
    train and manage complex healthcare systems.
  • Healthcare workers must be prepared to learn and
    adapt to the use of computer in healthcare.
  • Challenges Maintaining confidentiality
    interoperability consistent language and patient
    trust in security

Consider the possibilities
